To run it, unpack the files and then edit the conky config: between line 11 and line 20 is the information what you have to modify to make this clock run on your system and some suggestions what you might consider to change. Pretty easy also for beginners.

A 4-stone-24-hour version will follow in the future. Maybe also a set of different domino stones.
